redsn0w 0.9.10b8 adds the ability to backup arbitrary directories or files from your device into a zip file on your Mac or PC. The new button is Extras->Even More->Backup and it requires your device to be jailbroken with the afc2 service enabled (most jailbreaks include that). By default it will backup your activation records from /var/root/Library/Lockdown, which is useful for everyone taking advantage of today’s SAM unlock using Loktar_Sun’s trick (more on that in a later post!).

So in other words, you can now backup arbitrary directories, and RedSn0w will by default backup the /var/root/Library/Lockdown which is needed to preserve your activation ticket.

We’re anxious to see what else the Dev Team has to say about the SAM unlock. Once they chime in with a further update, we’ll be sure to divulge the details.

You can download RedSn0w 0.9.10b8 for Windows and Mac from our downloads page. For more information on RedSn0w in general, visit our dedicated RedSn0w page.
